> Please help me out in this. What is the latest versions of above mentioned libraries. To find the version of Python libraries, you can search https://pypi.org for the package and look at the "Release History". For feather, that's: https://pypi.org/project/feather-format/#history It looks like your Pandas DataFrame is storing those list columns as simple python objects (probably lists of integers), which have a lot of overhead at the row counts you have. You should find a more efficient representation for those. In PyArrow, we have a built-in List type for that (part of why the feather file is much smaller; it uses the Arrow format internally). But there might be a pandas / numpy solution to that, I'm not sure. -- This is an automated message from the Apache Git Service.
